The validity of emergency department influenza-like-illness (ILI) for laboratory-confirmed influenza in children
Content Type: Abstract
Syndromic surveillance systems use electronic health-related data to support near-real time disease surveillance. Over the last 10 years, the use of ILI syndromes defined from emergency department (ED) data has become an increasingly accepted… read more… to those from CC alone. The false positive fraction of all syndrome definitions was higher in younger children … permitting all non-commercial use, distribution, and reproduction in … ehtj11115 ehtj11120 ehtj11024 ehtj11060 ehtj11110 26-50 ehtj11034 ehtj11198 ehtj11174 ehtj11048 ehtj11154 … -
Monitoring Staphylococcus Infection Trends with Biosurveillance Data
Content Type: Abstract
Methicillin resistant staphylococcus aureus (MRSA) is a leading cause of skin and soft tissue infections (SSTI). Until recently, S. aureus pneumonia has been considered primarily a nosocomial infection, and was reported… read more… annual trend in the proportion of PI admissions due to S. aureus. Almost half (47.8%) of patients … in the proportion of SSTI diagnoses at EDs. However, we did not find an increasing annual trend in S. aureus … -
Syndromic Surveillance for Influenza in Washington State: A Local and Regional Perspective
Content Type: Abstract
We explored the utility of tracking emergency department (ED) visits for febrile illness as a proxy for influenza surveillance, from both a local and a regional perspective.… was lowest compared with King and Pierce counties and did not correlate as strongly with data from these two … the 5-17 year old age group (r=.84); the correlation for all other age groups was less than .65. CONCLUSIONS ED fever … activity, including laboratory influenza test results and all cause school absenteeism. ED fever visit trends for … -
Classification of Emergency Department Syndromic Data for Seasonal Influenza Surveillance
Content Type: Abstract
We evaluated several classifications of emergency department (ED) syndromic data to ascertain best syndrome classifications for ILI.… through 4/28/2007 and excluded one hospital that did not provide ED chief com- plaints. The weekly number of … including data from the diagnosis, where available, did not consistently improve the SNR. The correlation with … of the “CCFEVER” and “ANYFE- VER” categories, which did not lag behind RA. Us- ing an algorithm that switches … -
How Bad Is It? Using Biosurveillance Data to Monitor the Severity of Seasonal Flu
Content Type: Abstract
We sought to evaluate the validity of pneumonia and influenza hospitalizations (PI) data gathered by our biosurveillance system.… a patient and visit key. Data are transmitted daily, but due to delays in establishing diagnoses, may lag by up to … two data sources over time was greater than 0.95 across all age groups, and was highest among adults.

Systematic Comparison of Algorithms Used in Syndromic Surveillance
Content Type: Abstract
Varied approaches have been used by syndromic surveillance systems for aberration detection. However, the performance of these methods has been evaluated only across a small range of epidemic characteristics. Objective… read more… visits per day. We then simulated epidemics by creating all possible combinations of 3 different parameters: … syndrome. RESULTS Overall, timeliness was similar for all algorithms, with time to detection ranging between 2 and … after the start of the outbreak. When averaged across all outbreak parameters, the GLM had the best sensi- tivity … -
Data Quality
Content Type: Use Case
Problem Summary Data collection across a growing stream of contributing facilities and variables requires automated, consistent, and efficient monitoring of quality. Epidemiologists tasked with analyzing syndromic data need to be confident in the… read more… sources of (near) real-time health surveillance feeds (ie school-absenteeism, outpatient, OTC sales, etc). … and what level of skill do the users have?
